4 min read
On this page

In this lesson, you will learn:

  • The CMDB Health measures
  • How to set them for discovered classes
  • SNWR’s results

🔁 Quick look back: Last time: Finding and Merging Duplicates After Discovery. You learned how the London file server duplicate was found and merged.

1 The Problem: Quality Needs Measuring Every Day

Clear View’s data is good today. But next month:

  • A server might stop being discovered.
  • Required fields might go missing.

🎯 The problem: Data quality needs measuring every day, not just once.

👉 The fix: Set CMDB Health for discovered classes and track it in CMDB Workspace.

Table of health measures and results.
Figure 1. CMDB Health for SNWR’s server classes.

2 The measures

Key term: Completeness

Are required fields filled?

Key term: Correctness

Are there duplicates or orphans?

Key term: Staleness

Has the CI been updated recently?

💡 Good to know: Need a refresher? See Fundamentals › CMDB Essentials › CMDB Health & Maintenance for the Health dashboard.

3 Setting it up

  • Mark the fields that matter as required for health.
  • Set staleness to match the schedule, like 7 days.
  • Watch results in CMDB Workspace.

4 Project Clear View: How We Implemented It

📍 Situation: Hana wanted a way to see quality every day.

🧭 Decision: Set health for server classes and show her CMDB Workspace.

🛠️ Steps we took:

  1. Marked the must-have fields for health.
  2. Set staleness to 7 days for servers.
  3. Ran the health jobs.
  4. Showed Hana the results in CMDB Workspace.

✅ What we verified:

  • Server completeness is 88%, up from 41%.
  • No stale servers.

📁 Evidence: Health settings, evidence for AC-03.

5 Quick recap

  • Health measures completeness, correctness and staleness.
  • Set required fields and staleness per class.
  • Watch it in CMDB Workspace.
  • SNWR went from 41% to 88% complete.
